5.1.4 waves in the ear

Question 1

How does ur ear detect sound?

Answer 1

The outer ear gathers the sound wave and directs it to your ear drum which vibrates.
As the ear drum vibrates it makes the ossicles vibrate and pass it on the inner ear through the oval window.
Then your cochlea transmits the movements of the oval window to small hairs inside the cochlea which make nerves send a singal to your brain which processes the sound and you hear the sound.

Question 2

Why can you only hear in a range of particular frequencies?

Answer 2

The hairs in ur cochlea have different lengths and resonate at different frequencies of sound.
